The first hole 908 may be located on or in proximity to the first fastener structure 806. The release tool 912 may have an extended long apical part that fits into the first hole 908.

The first fastener structure 806 and the second fastener structure 726 are unfastened from each other when the release tool 912 is inserted into the first hole 908 and applies an unlocking action e. g. , a press and a twist on them. In some implementations, a microphone aperture 716 is located on a front cover plate 708 of the doorbell camera 106 to allow sound wave to reach a microphone concealed behind the front cover plate 708. A plurality of speaker openings 718 may be located at a bottom rim surface of the device housing 702 of the doorbell camera 106, and configured to broadcast audio messages e. g. , coming from a remote client device to a visitor near the mounting surface. When the doorbell camera 106 is mounted onto the mounting surface, the speaker openings 718 are not visible from a gaze of the visitor as the visitor is approaching or standing near the mounting surface.
